entrainment

(en-trayn -mĕnt) Any process that involves the sweeping-up and transport of material by a fluid. The effect is thought to occur around jets in radio galaxies. These jets are light, probably consisting of electrons and positrons, and generate surface instabilities as they sweep past the intergalactic medium. This leads to mixing, and the entrainment of heavier material, which affects the dynamics of the jet.

entrainment

[en′trān·mənt]
(chemical engineering)
A process in which the liquid boils so violently that suspended droplets of liquid are carried in the escaping vapor.
(hydrology)
The pickup and movement of sediment as bed load or in suspension by current flow.
(meteorology)
The mixing of environmental air into a preexisting organized air current so that the environmental air becomes part of the current.
(oceanography)
The transfer of fluid by friction from one water mass to another, usually occurring between currents moving in respect to each other.

secondary air motion

The motion of air in a room caused by the discharge of air from an air diffuser or any type of air outlet.
